Second, the external and internal factors affecting the cycle life of lithium-ion batteries are investigated in detail, including temperature, charge/discharge multiplier, charge/discharge cut-off voltage, cell performance inconsistency, solid electrolyte interphase (SEI) film, and copper foil.
Therefore, the experiment data showed that power lithium-ion batteries directly affected the cycle life of the battery pack and that the battery pack cycle life could not reach the cycle life of a single cell (as elaborated in Fig. 14, Fig. 15).

Among all power batteries, lithium-ion power batteries are widely used in the field of new energy vehicles due to their unique advantages such as high energy density, no memory effect, small self-discharge, and a long cycle life [, , ]. Lithium-ion battery capacity is considered as an important indicator of the life of a battery.
The charging and discharging processes of the battery are optimized. The capacity degradation is unfavorable to the electrochemical performance and cycle life of lithium-ion batteries, but the systematic and comprehensive analysis of capacity loss mechanism, and the related improvement measures are still lacking.
A major challenge in the field of early life prediction of lithium-ion batteries is the lack of standardized test protocols. Different research teams and laboratories adopt various methods and conditions, complicating the comparison and comprehensive analysis of data.
This includes the potential integration of thermal management factors into predictive models and utilizing scaled-up experiments or simulation studies to validate findings from small battery tests. A major challenge in the field of early life prediction of lithium-ion batteries is the lack of standardized test protocols.
